Really nice spacers, as you would expect at the price. Didn't weigh them, but happy with them regardless. I like the matte finish.
These spacers do the job, but do not match color or finish of my ENVE carbon stem or seatpost. I was willing to pay more for a better match. You are just better off going with pure black spacers and save some money. Product is not recommended at this price.
If your cockpit is Enve then why not the spacers ;-)
